South WS drivers beware: Seattle city crews have stepped up the drainage work at the south end of the Cali straightaway (Cali/Thistle) and, a block downhill, next to the Thistle/Northrop sinkhole that opened in the deluge before last December’s windstorm. Heavy equipment tore up more pavement today at Cali/Thistle (photo below) and the Thistle/Northrop bend is squeezed to one lane.
